This paper presents de-noising of PD signal using three different techniques; ANN, FFT and DWT. The objective of this paper is to yield the PD signal from the disturb signal which is the combination of PD and noise signal. These signals are generated using EMTP-ATP simulation environment. This research used the straightforward procedure in the de-noising technique. The accuracy of the de-noising is...
In this paper, a series of investigations on sensitivity and bandwidth for four types of Rogowski coil (RC) sensors was demonstrated. The proposed RC sensor design using acrylonitrile butadiene styrene material carries the advantages, such as lighter weight, robust, and higher temperature resistance. The prototype development first was carried out with the assistance of Solidwork 3D computer aided...
Insulation failure has been identified as one of the main reasons for transformer breakdown. As one the most important assets in the high voltage system, the loss of a power transformer will cause significant effects to consumers and on the system. The condition of the insulation can directly be correlated to the presence of Partial discharge (PD). Therefore, the ability to accurately detect and analyse...
